A method, system, and product are disclosed for indicating a power status
of multiple devices using hierarchically encoded indicators. Multiple
nodes are included within a data processing system. Each node includes a
different implementation of the devices. Each one of a first level of
power indicators are associated with a different one of the nodes. Each
one of a second level of power indicators is associated with a different
one of the devices. A power status of each node is indicated utilizing
one of the first level of power indicators. A power status of each device
is indicated utilizing the second level of power indicators.
